To all whom it may concern: I

Be it known that I, ARTHUR J. BASTIAN, a citizen of the United States, and a resident of Wilkinsburg, in the county of Allegheny and State of Pennsylvania, have invented a new and useful Improvement in Timing Devices, of which the following is a specification.

My invention relates to time-measuring devices, and particularly to electrically controlled means for giving a signal, when a machine has been in operation for a predetermined period of time.

One object of my invention is to provide a device of the above indicated character that shall indicate to a workman that his machine, such, for example, as a hot-press, has operated fora required period of time.

Another object of my invention is to provide comparatively simple and inexpensive means, having great durability and efliriency, for operating a number of such devices, whereby a workman who is in charge ,of a plurality of machines may be warned when each machine has been in operation for a predetermined period of time.

Heretofore, it has been customary to provide devices for the same purpose with a motor for each, thereby making the cost of installation more expensive and the cost of maintenance relatively greater.

I have provideda single motor, which operates a plurality of timing devices. The parts of each device are readily accessible and are so simple in design that little skill is required by a workman to operate and repair them. Each device rings a bell to attract the workmans attention to the machine and energizes an electric lamp to indi cate which of the machines has been in operation the requiredperiod of time.

Reference may now be had to the accompanying drawings, Fig. 1 of which is a view, in end elevation, of a timing device embodying my invention mounted on a hot press and driven by an electric motor. Fig. 2 is a view, in side elevation, of the timing device and the hot-press shown in Fig. 1. Fig.- 3 is a view, in end elevation,- of a simi Fries.

Fig. 4 is a view, partly in side elevation and partly 1Il-SCt1OI1, of the timing device shown in Figs. 1 and 2. Fig. 5 is a view, partially in end elevation and partially in section, of the timing device shown inFig. 4. Fig. 6 is a View, in side elevation, of a rocker shown inFigs. 4 and 5. Fig. 7 is a view, in end elevation, of the same. Figs. 8 and 9 are views, inside and in end elevation, respectively, of a shifting pin shown inFig. 4;.

Referring particularly to Figs. 1 and 2, a

timing device 1 embodying my invention is shown securely mounted on a hot-press 2 and is connected to. a synchronous motor 3 by a gearing 4: and a shaft 5. A bar or lever 6, attached to a movable base portion 7 of the hot-press 2, engages an arm 8 of a timing device 1. The motor 3 is mounted on a bracket 9 which is attached to the hotpress 2. An electric lamp 10 and a bell 11 are provided for producing signals by the timing device 1..

The gearing 4: comprises a pinion 12 that is mounted on the shaft of the motor3, a gear wheel 13, a worm screw 14, aworm wheel 15, a worm screw 16, a worm wheel 17, and a shaft 18. A gear wheel 19, mounted upon the shaft 18, engages a gear wheel 20 mounted upon the shaft 5.

In Fig. 3, the timing device 1 is mounted on a hotpress 2 and is driven by a shaft 5 which operates a plurality of similar devices. The shaft 5 is provided with a plurality of universal joints 21 to provide for the timing devices being slightly out of alignment, and it is driven by the motor3.

Referring to Figs. 4 and 5, the timing device 1, which is also shown in Figs. 1 and 2, comprises a case 22, made of some suitable rigid material, such, for example, as wood,

metal or micarta; the shaft 5 and a circular dial plate 23 fixedly mounted thereon by means of annular discs 24: and 25, screws 26 and a taper pin 27. A face plate 28, graduated with even numbers between zero and 120, and having a circular opening in which the dial plate 23 rotates, is attached to the be actuated by the dial plate 23 by causing the pin 30 to engage one of the sixty'holes punched therein. These holes are equidistant from the center of the dial plate 23 and are uniformly spaced with respect to each other.

A bar or knoeker 31 is pivotally mounted upon a pin 32 and engages a rocker 33, which is pivotally mounted upon a pin 33a. The movement of the bar 31 is limited by posts 34 and 35. A hammer 36 is secured to the rocker 33 by a bent arm 360. (see Figs. 6 and 7 of the drawings) and, when the rocker is actuated clockwise, it strikes the bell 11. A copper brush 37 attached to the rocker 33, engages a post 38 when the rocker is rotated clockwise and completes an electric circuit which comprises the electric lamp 10, rocker 33 and binding posts 34 and 38. Rapid movement of the rocker 33 is obtained by the manner in which its angular projection 39 engages a projection 40 of a shifting pin 41 (see Figs. 8 and 9 ofthe drawings). The shifting pin 41 is provided with a helical spring 4264 that maintains in contact relation the two projections 39 and 40 of the rocker 33 and the shifting pin 41, respectively. The rocker 33 is provided with two projections 42 and 43 between which some free movement is permitted the knocker 31. The outward movement of the .knocker 31 is resiliently resisted by a pin 44 provided with a helical spring 45.

The arm 8 of'the rocker 33 is so bent that it may be engaged by plate 45 that is attached to a bar 46. The arm 8 may assume positions 8a, 8b, and 8c, in accordance with the manner in which the projection 39 of the rocker 33 engages the projection 40 of the shifting pin 41.

The bar 46 is pivotally mounted in a bracket 47 of the lever 6. A rod 48, provided with a helical spring 49, is resiliently mounted in a bracket 50, forming part of the lever 6, and is attached to the bar 46.

Figs. 6 and 7 are vlews, in side and in end elevation, respectively, of the rocker 33. An

angle of is formed by the two intersecting faces of the projection 39.

Figs. 8 and 9 are views in side and in end elevation, respectively, of the shifting pin 41 and its projection 40. The two faces of the projection 40 intersect at an angle of 90.

When a plurality of hot-presses are started in operation, it is necessary that a warning be given when various periods of time have elapsed, depending upon the work to be performed by each machine. To-obtain this. the motor 3 is started, which causes the shaf 5, the dial plate 23 and arm 29 of each ti1n ing device 1 to turn in a clockwise direction once in two hours.

The operator, having placed an object, such, for example, as a commutator, on one of the hot-presses, and desiring that it be in the machine for thirty minutes, moves the pointer 29 to the graduation 30 marked upon the face plate 28. The pointer 29 begins to rotate in a clockwise direction and, in thirty minutes thereafter, will return to the zero graduation.

When the operator raises the base portion 7 of the hot-press 2, the lever 6, which is attached thereto, rises with it, and the plate 45 engages the arm 8 of the rocker and thereby causes it to move inwardly to position 8a. The rotation of the rocker 33 to the left removes the hammer 36 a slight distance from the bell 11.

lVhen the pointer 29 rotates to zero, the

knocker 31 is forced outwardly and it, in turn, by engaging the projection 42 of the rocker 33, causes the rocker to assume position 85 which is that shown in the drawing. A relatively slight movement beyond this position results in the projection 39 rotating beyond projection 40 of the shifting pin 41, and the spring 42a forces the pin 41 downwardly, thereby causing an accelerated movement of the rocker to position 80. In this position, the bell 11 is struck by the hammer 36, the copper brush 37 engages the posts 38 and the projection 42 engages the post 34.

In the above position of the rocker 33, the

electric lamp 10 is energized by the completion of a circuit comprising the rocker 33, copper brush 37, binding posts 34 and 38, and the electric lamp 10. The electric lamp will continue to burn as long as the rocker 33 is in the position 80. By having the bar 46 pivotally. mounted on the lever 6, the pin 8 of the rocker 33 will not be damaged, if it fails to move when engaged by the plate 45.

The operations that have been previously described are repeated each time an article is baked in a machine. The only operations that are required are to reset the pointer 29 and to place the article properly in the machine. The device is so designed that it is immaterial what angular position the dial plate 23 occupies, as the graduations are marked upon the stationary face plate 28.

If it is desired to inspect the interior of a timing device, the face plate 28 may readily be detached from the case 2.

From the above description it may be seen that the chief advantages'of my inven tion are that a single motor may operate a plurality of timing devices and that the signals are such as to insure notice to the workman that the desired t me of operation of the machine has expired, and the electric light prevents the workman from selecting the wrong machine.

While I have shown my invention in a preferred form, it may be subjected to slight modifications, and, therefore, I desire to be limited only by the scope of the appended claims.
